:-( :-( :-( when I ski hard after a few runs I sit down and won't move until it passes, about forty five minutes. then I feel fine except that I could go to sleep. I go to the ski patrol and have all the tests done 02 stats normal,blood pressure 126/81-pulse 48,blood 104. one time I was shoveling snow and it happened before skiing. I have T.B.I. from an accident and have to where glasses, I do have wobbling in my eyes win I walk, my doctor lowered my blood pressure meds and it has seemed to help but I still feel it a little.
